Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heating cooker having a gas stand function that is installed together with kitchen appliances installed in the kitchen, such as a sink or a cooking table.

Configuration of Conventional Example and its Problems For example, a conventional stove stand with built-in cooking utensils will be explained with reference to FIG.

When the heating cooker 1 at the bottom of the appliance is used as a gas oven, the cooling fan 4 located in the space 3 also rotates in conjunction with the drive of the convection fan 2 inside the refrigerator. As the cooling fan 4 rotates, outside air is actively taken in from the air supply port 5, and a sufficient amount of combustion air is supplied to the oven gas burner 6, ensuring more complete combustion, and the wind from the cooling fan 4 Therefore, the temperature rise of various electrical control parts including the magnetron 7 is suppressed, and stable operation of the equipment is achieved. In addition, the wind that has cooled the electrical control parts is also affected by the draft effect of the exhaust gas discharged from the exhaust stack 8, cools the partition plate 9 and the exhaust stack 8, rises toward the exhaust port 10, and is discharged from the exhaust stack 8. The exhaust gases mix and are discharged from the exhaust port 10 to the outside of the device. Exhaust gas discharged from the exhaust port 10 is discharged from the upper opening 11 of the exhaust pipe 8 at an angle slightly toward the front of the device as indicated by arrow a in the drawing.

However, in this type, the air around the heating chamber is exhausted from around the exhaust pipe 8, but it is not distinguished from the air intake of the cooling fan, so the cooling effect is poor and the temperature of the outside plate of the appliance tends to rise. Ta. Furthermore, there was no top plate, etc., and although it was divided by a partition plate 9, there was no consideration for air insulation, so too much heat was trapped.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks by efficiently discharging the exhaust efficiency of the heating cooker and the hot air around the appliance, keeping the body temperature of the appliance low when the appliance is in use, and ensuring that the temperature of the cooking appliance is low. The purpose is to keep the overall temperature of the gas appliance, including the body temperature, low even when the gas appliance is mounted.

Structure of the Invention In order to achieve the above-mentioned object, the cooking device of the present invention uses a space between a top plate on which a gas stove or the like is placed and a cooking device 12 consisting of a heating chamber and a combustion chamber located below the top plate to accommodate a gas stove, etc. A high-frequency oscillator that supplies high-frequency power into the heating chamber and a partition wall with an opening at the rear of the heating chamber communicate with the space provided between the back plate facing the rear of the heating chamber and the chimney that discharges waste gas. On the opposite side of the partition wall in the combustion chamber, a wall surface with an open center is provided, and a hot air circulation fan is placed next to this wall surface approximately in an extension of the center of the opening. a duct that communicates the rotating outer circumferential side of the circulation fan and the heating chamber;
A main exhaust port for gas that communicates with the combustion chamber and a sub-exhaust passage that communicates with a sub-exhaust hole provided on the wall of the heating chamber are provided, and a portion of the sub-exhaust passage is filled with water vapor in the exhaust gas or heated gas. A sensor or temperature sensor that is sensitive to the gas generated from the material is installed, guided through a duct from the confluence of the main exhaust air port and the auxiliary exhaust passage, and connected to the removable chimney. It is characterized by communicating with the surrounding space, and further communicating the space between the outer periphery of the cooker and the top plate with the area around the chimney, so that exhaust gas is discharged through the multiple tubes. .

DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in FIGS. 2 to 4.
Explain based on the diagram.

In FIG. 2, a main body 1 with a built-in cooking chamber 12 is shown.
3. Behind the top plate 14 on the top surface of 3 is a piping cover 15.
and a back guard 16. The piping cover 15 has a space as an exhaust port from the cooking device 12 and a space for the gas piping 17, and the top surface has an exhaust port cover 18 of the cooking device 12,
A cock 19, a hose end, or a gas connection port 20 are provided. The top plate 14 can be used as a cooking table, and a gas stove or the like is placed thereon, and gas pipe supply is controlled via the cooktop 19 and hose end 20. When connecting to the stove,
When connecting with a flexible piping connection or a fixed pipe, the flexible piping connection or fixed pipe is installed from right to left in the front recess of the gas pipe cover 15 shown in FIG. 2, and is connected to the connection port of the gas stove. In FIG. 3, the exhaust tube 22 fits into the exhaust connection port 12 of the heater 12 at the height of the top plate 14.
There is a lid 19a on top of the gas tank 19, and the gas tank can be operated by opening the lid 19a.

In FIG. 3, 23 is a heating chamber, 24 is an upper wall of the heating chamber 23, and 25 is a main exhaust port communicating with the heating chamber 23, which is provided on the upper surface of the combustion chamber 26. Reference numeral 27 denotes a hot air circulation fan located on one side of the combustion chamber 26, which blows hot air from the gas burner 28 into the heating chamber 23, sucks it in from the inside, circulates the hot air through the partition wall 29, and circulates the hot air inside the combustion chamber 26. to a uniform heating temperature. Separately from the main exhaust port 25, the upper wall 24 of the heating chamber 23 communicates with a sub-exhaust passage 30. A chimney 31, which is a main exhaust gas passage, communicates with the outside of the main body through a discharge port 32. In Figure 4, 3
3 is a cooling fan, and the wind from this cooling fan 33 cools the magnetron 34.

When the appliance is used as a gas oven, part of the hot air exhaust gas in the heating chamber 23 passes through the sub-exhaust passage 30, and when the appliance is used as a microwave oven, the above-mentioned magnetron The air that has cooled the air 34 passes therethrough, including water vapor generated by the object to be heated (not shown).

According to the invention as described above, the following effects can be obtained.

(1) Connect the exhaust air from the heating chamber to a removable chimney, communicate the space around the outside of the heating chamber with the space around the outside of the chimney, and further communicate the space between the outer periphery of the cooker and the top plate with the area around the chimney. By doing so, the exhaust gas is discharged through the tubes with a multi-layered structure, so that high heat is less likely to leak outside, and the temperature of the cooker body can be kept low.

(2) The space between the top plate on which the gas stove, etc. is placed and the cooking device consisting of the heating chamber and combustion chamber below the top plate, and the space between the back plate facing the rear of the gas stove, etc. and the chimney that discharges waste gas. By communicating with the space provided in the front panel, cold air is supplied from the front and exhausted from the top, making it possible to keep the temperature of the back plate and the top plate low. Therefore, even when the gas stove is installed, the temperature of the gas stove can be raised or lowered.
